Recently a Windows 98 started prompting "Please Insert a Diskette for Drive B" during a DOS application backup and at Shutdown. There is no B drive configured in the Bios or within Windows and the DOS program configuration is set to A (and has not been changed for years). Norton Antivirus found and corrected the kak.worm but detects no other virus. How do I fix this problem?

Even though there is no B: drive configured, could the "swap floppy drive" option in CMOS being enabled cause the situation.

I changed the CMOS to A only with no swapping. It did not fix the problem. Thanks for the try.

I had a similar problem with a NT workstation. I fixed the problem by disconnecting the existing A: drive and rebooted the machine. On boot up I received some error stating that changes had been made and that I must "validate" them. I pressed F4 to validate the changes and finished booting. Then I shutdown again and reconnected the A: drive. Again I rebooted and validated my changes and the B: drive was gone.

I disconnected the A drive, rebooted, and still the same problem. So I removed the floppy driver and controller and rebooted, and still the same problem. The prompt for the B drive just won't go away. Thanks, it was a great idea.

Hi you might try this reboot to the start menu got to command promt only click enter when you get the C: promt tpye fdisk /mbr and click ok. This will remove you master boot record and reinstall it fixed. rockyolson@chater.net

Try using the file find advanced option and search for B:, this will bring up all files referencing B:. Edit them changing the B to an A and save.
You will probably find a reference in the autoexec.bat for DOS.

(Someone probably copied from one 3.5 to another without using the C or D drive)

Good Luck!

I recommend staying away from modifying or *DELETEING?* your MBR. Could end up being more trouble then its worth.

If you're comfortable with Regedit, search for MRU and see if there are any references to a "B" drive. If so, they can be safely deleted. Reboot your PC and this issue will go away *if* the MRUs had "B" drive entries.
